这片文档旨在帮助没有经验的用户快速入门\LaTeX 。文档使用尽可能简短的内容将\LaTeX 中最常用的概念和功能讲清楚，同时从多数\LaTeX 用户的需求出发，讲解如何在\LaTeX 文档中插入公式、插入代码、标注参考文献等。需要注意的是\LaTeX 中存在很多种不同的方法来完成同一件事，例如标注参考文献可以使用\verb|thebibliography|环境，也可以使用功能强大而复杂的BibTeX。不同的方法没有绝对的优劣，只有不同的适用情况。由于这是一篇入门向的文档，因此这篇文档会选择最容易上手或是泛用性最强的方法进行讲解。比起lshort，这篇文档尽量不涉及细碎的细节，不会讲解一些高级用法，但是会加入一些笔者个人的经验。这些经验谈不上是什么教科书式的做法，但的确足够实用，可以解决在写\LaTeX 时的许多常见问题。可以说这篇文档的性质介于比较随意的博客和比较正式的教程之间。

作为一篇很短的教程，本文只能带着大家走马观花地了解一下\LaTeX 究竟是什么，里面大概有什么东西。看完了这个教程只能说可以自己摸索着开始写了，离真正的熟练还有很远的区别。受长度限制本教程甚至连许多常用的东西都没有包含进去。建议进一步阅读\LaTeX 的半官方入门文档\textit{lshort}。对于大多数情况，\textit{lshort}足够担任一本不错的教程与参考书了。\textit{lshort}中文版可由以下链接获得：

This document aims to help users without experience to quickly get started with LaTeX. The document uses the shortest possible content to explain the most common concepts and features of LaTeX, while also explaining how to insert formulas, code, and annotate references in LaTeX documents, starting from the needs of most LaTeX users. It is worth noting that there are many different ways to accomplish the same thing in LaTeX, such as annotating references can use the \verb|thebibliography| environment, or more powerful and complex BibTeX. There is no absolute advantage or disadvantage among different methods, only different situations. As this is an introductory document, this document will choose the easiest to start or the most general method for explanation. Compared to lshort, this document does not involve too many details, does not explain some advanced usage, but does include some personal experience of the author. These experiences may not be textbook-style practices, but they are indeed practical enough to solve many common problems when writing LaTeX. It can be said that the nature of this document is between a relatively casual blog and a more formal tutorial.

As a short tutorial, this article can only give a general understanding of what LaTeX is and what it contains. After reading this tutorial, you can start writing on your own, but there is still a long way to go before true proficiency. Due to the length limitations of this tutorial, many commonly used things are not included. It is recommended to further read LaTeX's semi-official beginner document \textit{lshort}. For most cases, \textit{lshort} is enough to serve as a good tutorial and reference book.
